My expertise lies in the MERN stack, TypeScript, Python, and Java, complemented by a strong command of cloud platforms such as AWS, GCP, and Azure. I am passionate about clean architecture and test automation, and I thrive in leading cross-functional teams to deliver production-ready solutions that handle over 200K users.

Throughout my career, I have successfully improved system performance by up to 45% and have implemented innovative solutions that enhance user experience and operational efficiency. My role at KYC Hospitality involved optimizing a React/Next.js frontend and migrating infrastructure to AWS, resulting in significant cost reductions and improved deployment reliability.
